MNHN Jg WIT/158858 A TTUBIVEYS in bearings 46 on members l1a of the frame l'l there is a shaft 47; and journaled in bearings 48 on members l0a of the frame 10 there is a shaft 4f). The shaft 37 is connected with the shaft 47 by means of a sprocket chain 50 which is disposed around a sprocket wheel 5l on the shaft 37 and a sprocket wheel on the shaft 47, the sprocket wheel 5l being mounted on a clutch member 51 which will rotate with the shaft 37 when it is engaged -by its companion clutch member 51b keyed to the shaft 37. They clutch member 51i is actuated by a lever 51.c which is controlled by a lanyard 51, lVhile the shafts 47 and 49 may each rotate in one direction to raise the plowshares, the said shafts are normally prevented from rotating in opposite directions by pawls 47a and 49a which engage ratchet Wheels 47b and 49b secured to the `shafts 47 and 49. rI`he pawls 47a and 49 may be freed from the ratchet wheels 47b and 49b bythe lanya-rds 47c and. 49C. The shaft 49 is connected with the shaft 34 by a similar sprocket chain 50 and similar spocket wheels 51 and 5:2, which will operate in a shnilar manner. The sets of plowshares 42 and 43 are connected with the shafts 49 and 47 by meansl of chains 53, which are secured to the plowshares and are disposed around pulleys 54 secured to the shafts 49 and 47.

It will be seen that with this construction, when the shafts 30 and 3l. are rotated to drive the tractor in one direction, the

plowshares at one end of the tractor may be lowered and thc plowshares at the other end of the tractor vmay be raised, and that 'when the direction of rotation of the shafts 30 and 31 lis reversed to drive the tractor in the opposite direction, the plowshares which have been raised may be lowered, and the plowshares which have been in contact with the ground may be raised to inoperative position. This may be done by throwin into operative position the clutchv mem er l". On the frame l() as illustrated in the drawings, there is mount ed a motor 55 which is connected by means of gearing 56 with the shaft 30. The engine shaft is also preferably connected by means of gearing 57 with a shaft 58A journaled in bearings 59 in the frame 10, this shaft 58 being provided with a pulley 60 which may be used for a variety of purposes.

One of the frames, preferably the frame 10, Ais provided with two yvertically extending steering shafts 461 and 62, one spaced in front of the other, the steering shafts 61 and 62 62, There is a bevel gear (S4 on the shaft 6i. and a bevel gear 65 on the shaft 6:2 the said bevel gears 64 and 65 meshing with being journalcd in bearings Gil. The steering shafts have steering wheels (51a and gears 6G and 6701i the shaft 68 disposed longitudinally of the frame l() and jourv naled in bearings (if). The said shaft (38 has a worm which meshes with a worm wheel 7l on a 'vertical shaft 72. ik pulley or sprocket wheel 'is secured to the shaft 72 which is engaged by a' chain 76 disposed around pulleys 77 on the frame l0. The ends of this chain 76 are secured at 78 to the sides of the frame 1l, turn-buckles 7S) bcing provided fortightening the chain 7G.

Disposed between the shafts (31 and 62 there is journaled al post 73 having a seat 74, it being possible to rotate the post so that the operator may face the steering wheel 6la or the steering wheelV 62a, as desired. In either case it is possible for the operator by turning the steering wheel in front of him to draw up the chain 76 at one side of the tractor for steering purposes.` The lanyards 51d are operated by levers 80.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1..y In a tractor plow, two frames disposed one in front of the other and pivoted to gether on a vertical axis, traction wheels on the frames, means for driving simultaneously the traction wheels on. the two frame's,` two 'sets ofV agricultural implements, one set movably mopnted on eachv frame, and means operable by' he driving means at the will of the operator for raising one set of agricultural implements and for lowering the other set when the tractor plow is moved in one direction.

2.` In a tractor plow, two frames disposed one in front of the other and pivoted together4 on a vertical axis, tractor wheels on which the, frames are mounted, a longitudinal bearing on each frame, two shafts one journaled in each bea-ring, means disposed substantially in alinement with the pivot by which one shaft is adapted to drive the other wheels secured to the third mentioned shafts,

sprocket chains connecting the first mentioned sprocket wheels with the second inentioned sprocket wheels, tw'o sets of agricultural implements movably mounted in opposite directions one on each frame, two lekible means one connecting each agricultural implement with one of the third mentioned shafts, and clutch means for securing the sprocket. wheels mounted on the second men` tioncd shafts for rotating therewith.

3,. In a tractorplow, two frames disposed one in front of the other and pivoted together on a vertical axis, traction wheels on the frames, twosets of .agricultural implements one set morably mounted on eachA shafts one mounted on each frame, gearing connecting the first .shafts with the second mentioned shafts. gearing connecting the last mentioned shafts with the -traction wheels. two additional shafts one jonlnaled in hearings in each frame. two sets ol' agrieultural implementsI movably mounted in op| o ite directions one on each frame, two llexihle means one connecting each agricultural implement with one of the third mentioned shafts, and means` hy which the second shafts are adapted to rotate the third -shafts at the will ot' the operator.
